Definitions

  • the invention relates to a fiber excellent in cool contact feeling which is excellent in hand and skin touch and capable of preventing unpleasant feeling in the wet state and a woven fabric, clothing, and underwear excellent in cool contact feeling and obtainable by using the fiber excellent in cool contact feeling.
  • the fibers comprising resins into which hydrophilic groups such as carboxyl and hydroxyl are introduced can be exemplified as the fibers having the improved water absorption property.
  • the fibers comprising resins in which fillers having high heat conductivity are kneaded and fibers subjected to surface coating treatment can be exemplified as the fibers having the improved heat conductivity.
  • the fibers are scarcely distinguished from untreated ones in an actual sensory test by human being and cannot give them cool contact feeling.
  • Patent Document 1 discloses a fiber having cool contact feeling obtained by making the fiber retaining porous inorganic particles enclosing a water-absorbing polymer.
  • the fiber has surely sensible cool contact feeling.
  • it is required to add a large quantity of the porous inorganic particles to give sufficient cool contact feeling and accordingly, the hand and skin touch is adversely affected and thus the fiber cannot be used for underwear.
  • Patent Document 1 Japanese Kokai Publication 2002-235278
  • the invention is a fiber which contains a thermoplastic elastomer and an inorganic filler.
  • a thermoplastic elastomer and an inorganic filler.
  • a fiber obtained by spinning a thermoplastic elastomer is excellent in cool contact feeling in the case of using the fiber for clothing.
  • the fiber containing a thermoplastic elastomer is used for clothing, although the clothing are excellent in cool contact feeling, they become sticky or inferior in skin touch in the wet state owing to sweat and the like and therefore, in the case the fiber is used for clothing having direct contact with the skin such as underwear, it causes the new problem of unpleasant feeling.
  • an inorganic filler to a fiber containing a thermoplastic elastomer makes it possible to prevent unpleasant feeling at the time of wetting in the case the fiber is used for clothing and to give excellent hand and skin touch and therefore the fiber is preferably usable for clothing particularly underwear, and accordingly have accomplished the invention.
  • thermoplastic elastomer is not particularly limited, however a polyamide type elastomer and/or a polyester type elastomer is preferable.
  • the polyamide type elastomer is not particularly limited and examples are polyether block amide copolymers, polyether amide copolymers, and polyester amide copolymers. They may be used alone or two ore more of them may be used in combination.
  • Commercialized polyamide type elastomers among them are, for example, Pebax (manufactured by Arkema), UBE Nylon (manufactured by Ube Industries, Ltd.), Grilon ELX and Grilamid ELY (manufactured by Ems-Showa Denko KK), Daiamid and Vestamid (manufactured by Daicel-Degussa Ltd.).
  • the polyester type elastomer is not particularly limited and examples are polyether ester copolymers and polyester ester copolymers. They may be used alone or two ore more of them may be used in combination.
  • Commercialized polyester type elastomers among them are Grilux (manufactured by Dainippon Ink and Chemicals, Inc.), Nouvelan (manufactured by Teijin Chemicals Ltd.), Pelprene (manufactured by Toyobo Co., Ltd.), Hytrel (manufactured by Du porlt-Toray Co., Ltd.), and Primalloy (manufactured by Mitsubishi Chemical Corporation).
  • polyether block amide copolymers represented by the following formula (1) are particularly preferable since they are suitable for obtaining fibers remarkably excellent in cool contact feeling, excellent in spinning property, and suitable for producing a woven fabric, clothing and underwear which is light owing to having a light specific gravity.
  • Commercialized products of such polyether block amide copolymers may be, for example, Pebax (manufactured by Arkema).
  • PA represents polyamide and PE represents polyether.
  • thermoplastic elastomers alone may be used, however, a fiber containing only a thermoplastic elastomer as the resin component generally has a sticky feeling and sometimes becomes difficult for spinning and therefore another resin may be used in combination with the thermoplastic elastomers.
  • the fiber excellent in cool contact feeling of the invention contains further an inorganic filler. Addition of the inorganic filler forms very small roughness in the surface of the fiber and reforms the fiber surface, so that the sticky feeling, which is a characteristic of the thermoplastic elastomers in the wet state, can be prevented and in the case the fiber is used for clothing, the skin touch of the clothing in the case of putting on the skin and the releasing property at the time of taking off the clothing can remarkably improved. Further, since the sticky property of the fiber can be lowered, the spinning property at the time of producing raw yarns can be improved.
  • the inorganic filler is added not for providing the cool contact feeling but for preventing the sticky feeling at the time of wetting, it need not add a large quantity of the inorganic filler and even if the fiber is used for clothing, the addition does not cause adverse effect on the hand and skin touch.
  • the inorganic filler is not particularly limited and examples may include mineral type pigments, such as calcium carbonate such as light calcium carbonate and heavy calcium carbonate, barium carbonate, magnesium carbonate such as basic magnesium carbonate, calcium sulfate, barium sulfate, titanium dioxide, iron oxide, tin oxide, titanium oxide, zinc oxide, magnesium oxide, ferrite powder, zinc sulfide, zinc carbonate, aluminum nitride, silicon nitride, Satin White, diatomaceous earth such as fired diatomaceous earth, calcium silicate, aluminum silicate, magnesium silicate, silica such as amorphous silica, amorphous synthesized silica, and colloidal silica, colloidal alumina, pseudo boehmite, aluminum hydroxide, magnesium hydroxide, alumina, hydrated alumina, litopon, zeolite, hydrated halloysite, clay, hydrotalcite, aluminosilicate, talc, pyrophyllite, sme
  • inorganic fillers are not particularly limited and examples are finite forms such as spherical, needle-like, plate type forms and the like, or nonfinite forms.
  • the preferable lower limit of an average particle diameter of the inorganic fillers is 0.20 ⁇ m, and the preferable upper limit of that is 3.00 ⁇ m. If the average particle diameter is less than 0.20 ⁇ m, the effect to improve the unpleasant feeling such as sticky feeling at the time of wetting sometimes becomes insufficient and if it is more than 3.00 ⁇ m, the hand and skin touch may possibly be deteriorated in the case the fiber is used for producing clothing or the strength of the fiber may be decreased in some cases.
  • the preferable lower limit of the content of the inorganic filler is 2% by weight, and the preferable upper limit of that is 30% by weight. And the more preferable upper limit is 7% by weight. If it is less than 2% by weight, the effect to improve the unpleasant feeling such as sticky feeling at the time of wetting sometimes becomes insufficient and if it is more than 30% by weight, the strength of the fiber may be decreased. And the spinning property may be decreased in some cases.

  • the preferable lower limit of a q max value of the fiber excellent in cool contact feeling of the invention is 0.20 J/sec/cm 2 . If the q max value is less than 0.20 J/sec/cm 2 , most subjects do not feel cool contact feeling even if a sensory test is performed.
  • the more preferable lower limit is 0.21 J/sec/cm 2 and the further preferable lower limit is 0.22 J/sec/cm 2 .
  • the q max value is defined as a peak value of the heat flow quantity of stored heat transferring to a sample at a lower temperature in the case a prescribed heat is stored in a heat plate with a specified surface area and a specified weight and immediately after the heat plate is brought into contact with the sample surface.
  • the q max value simulates the body heat removed from the body by the sample when clothing is put on and it is supposed that as the q max value is higher, the body heat removed from the body is higher and the cool contact feeling is more excellent when the clothing is put on.
  • the preferable lower limit of the heat conductivity of the fiber excellent in cool contact feeling of the invention is 1 ⁇ 10 -3 °C/W ⁇ m 2 .
